Dear Ben,

Thank you very much! Now that I know it is possible, I will carefully read the manual and solve the problem!

Sincerely,
Xiaosong

The default settings for plot_surface() yields an surface with the same color. There are multiple ways to color the surface, either by supplying color information yourself via "facecolors", or turning on the "shade", and/or providing a "lightsource" object for custom shading. Unfortunately, the docs are pretty sparse in this area, but hopefully this will help.

https://matplotlib.org/api/_as_gen/mpl_toolkits.mplot3d.axes3d.Axes3D.html#mpl_toolkits.mplot3d.axes3d.Axes3D.plot_surface
There are some examples of using some of these keyword arguments here: https://matplotlib.org/examples/mplot3d/index.html

Dear Ben,
 
Thank you very much! I guess so and I will check that! I previously saw some examples but thought colour could only be the same at the same height. But this may not be true. The cubes may be also helpful!
 
Thank you very much for your help!
 
Sincerely,
Xiaosong

plot_surface() in mplot3d can ultimately do what you want, but you need to provide it the isosurface. I think scikit-image can provide that information with its marching cubes function.
 
Does that help?

Hi Everyone!
 
May I ask a question. Is it possible to plot the 3D iso-surface figures? Like the figures plotted by isosurface in MATLAB?
 
https://www.mathworks.com/help/matlab/ref/isosurface.html
 
Or like the 1st figure in 
 
https://en.wikipedia.org/wiki/Atomic_orbital.
 
I need this because I would like to plot the configure of target molecular orbitals using the data calculated from first-principle calculation. I have looked through the examples of the website. There are only examples similar to this but not the same?
 
Thanks very much!
 
Sincerely,
Xiaosong
